Question

Find each value if $f\left(x\right)=5x-9$

$f\left(-2v\right)$

Step-by-Step Solution

Answer

The value of $f\left(-2v\right)$ is $-10v-9$.

Step 1 – Putting value of x

We will put $-2v$ in place of x to determine the value of the function.

Step 2 – Simplifying the given function

As, we have:

$f\left(x\right)=5x-9$

We will put $x=-2v$:

$\begin{array}{l}f\left(-2v\right)=5\left(-2v\right)-9\\ f\left(-2v\right)=-10v-9\end{array}$

Step 3 – Determining the final answer

$f\left(-2v\right)=-10v-9$
